Previous Year Question (PYQs)
In the middle of the confounded desert, there is the lost city of “Ash”. City is 120 miles from start. Each person can carry enough rations for 5 days and max travel per day is 30 miles. Need to reach the city, stay overnight, and return to the coast without running out of supplies. Minimum persons needed?
Solution
Distance one-way $=120$ miles $=4$ days.
Round trip with overnight $=4+1+4=9$ days for at least one person.
Since each carries only 5 days, support persons must relay supplies and return.
Minimum possible group that can manage relay + return safely is 4 persons.
